Historical IGCC development – 1/2 The problem with traditional coal

• “Dirty”

o washing discard,

o water pollution,

o air pollution,

o slagging

o Fouling

o Negative by products (tar, contaminated ashes…)

• Inefficient

• Maintenance

• Long implementation time

• Difficult to finance

Historical IGCC development – 2/2

• IGCC development focused on large (250MW-600MW+) size

high grade bituminous coal

10-15% total moisture, 10% ash

Heating value of 6,500 kcal/kg (27.2 GJ/kg) (HHV) as feedstock

• Entrained Flow gasifiers from GE, Shell, Conoco-Phillips, Siemens, MHI

Limited to export quality bituminous coal

Coal Fuel Cost of $160-170+ per ton

• CAPEX with ‘F-Class’ based $3800-$4400/kW (gross output)

• IGCC Net Efficiency varies from 37-38%

• TOTAL 20 year (coal to bus-bar) Variable+Fixed Cost of Electricity (Var+Fixed CoE) $75/MWh (excludes cost of finance or amortization)

iGAs value proposition

Feedstock flexibility - the worse the quality, the better the economics

Option for methanol production – transportable energy

Positive by-products with commercial value – ash, sulfur, CO2

Expandable blocks of power, low real estate cost – 185 x 235 m

Expected $0.08 to $0.12 per kWh

Better efficiency than traditional coal – maximizes fuel value

Creates local employment (facilitating permitting)

Emissions within EU standards - eligibility for international financing

iGAS ® technology (Registered by SES as U-GAS® )

iGAS is a unique, proven technological gasification process that adresses the challenge of creating energy from low cost and quality coal and biomass feedstocks

• Experienced - Originated in US at Gas Technology Institute (GTI) and perfected over 40+

years Two commercial projects in China

• Fuel flexible – all ranks of coal & biomass, feedstock composition can be varied without

mechanical changes

• Simple - low-cost design, no movements in “hot process”

• Efficient - Low water / steam usage , Can operate at high pressure

• Reliable - Low Maintenance

• Clean - improved environmental performance, No tar or other negative by-products

• Adaptable - Small to large plant range ability

iGAS technology advantages

Fluidized bed advantages over fixed/moving bed

1. Fixed/moving bed carbon conversion efficiency is lower due to low process temperature

2. Fixed/moving bed temperature profile is non-uniform promoting generation of tars, oils and

other negative

3. Fixed/moving bed cannot handling fine material, creating production waste
